Firebird 4 has invalid libtomcrypt.so?

[Attila Molnár]

Hi *!

When IBX try to load "../FB40/lib/libfbclient.so.4.0.4" with Lazarus/IBX I get an error

"/home/amolnar/Programs/GDB3sBR/FB30/../FB40/lib/../lib/libtomcrypt.so.1: file too short"

Firebird-4.0.4.3010-0.amd64.tar.gz from the official download.

(I did not run the install.sh, just extracted the package to FB40 folder. I want to ship FB with my program and use in embedded.)

Using Firebird-3.0.11.33703-0.amd64.tar.gz with Lazarus/IBX works fine.

(after apt-get libtommath1)

What is the issue? It the libtomcrypt.so.1.0.1 really wrong in the package?

Thank You!

If you are putting Firebird in a non-standard location (which I often do when testing), it is usually a good idea to set the FIREBIRD environment variable to the installation root, and the LD_LIBRARY_PATH environment varibable to $FIREBIRD/lib. Have you done this? If not then try doing this.

Is it a link or regular file ?

This must be a link (to libtomcrypt.so.1.0.1) but what happens actually
I can't know. In out package:

# ldd libtomcrypt.so.1
        linux-vdso.so.1 (0x00007ffcb4d62000)
        libc.so.6 => /lib64/libc.so.6 (0x00007f1d5e027000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f1d5e53b000)

ie. libtomcrypt.so.1 is correct ELF.

I can't set the environment variable, because I use many other embedded and service Firebirds on the machine.

It can be done programmatically in your application.

I replaced the libtomcrypt.so.1 link in FB40/lib to the actual libtomcrypt.so.1.0.1 file, and now it works as expected.

[Attila Molnár]

Nope, on Linux setting the environment variabe is not possible. Linux does not allow it, so there is no function for it in Lazarus/Free Pascal.

[Virgo Pärna]

Very basic way to do it for specific command is (works in bash):
FIREBIRD=/path/to/firebird /program/to/be/executed

It is the client program that needs to have the env vars set, including the case where Firebird runs in embedded mode. Before you invoke the program:

1. From a command line shell

export FIREBIRD=/home/amolnar/Programs/GDB3sBR/FB30/../FB40

export LD_LIBRARY_PATH=$FIREBIRD/lib

2. From the Lazarus IDE

Select Run->Run Parameters and click on the "Environment" tab

Add the two environment variable separately (and without the export) to the list of "User Overrides"

In both cases, I would give the full absolute path.

Lazarus can call C functions and there is

I guess, when you unpack archive, the file type for libtomcrypt.so.1 was lost and
what should be soft link became a regular file. The correct fix for this issue would
be to re-create soft link, I believe. And check why the problem happens at all.
